[PATCH] Compile debug/stack_chk_fail_local.c with stack protector

[Florian Weimer]

The resulting object file is statically linked into applications, so
it is desirable to have (formal) stack protector coverage there.

2018-07-05  Florian Weimer  <fweimer@redhat.com>

	* debug/Makefile (CFLAGS-stack_chk_fail_local.c): Remove
	$(no-stack-protector).  stack_chk_fail_local.c can be compiled
	with stack protector enabled because there is no risk of infinite
	recursion.
